SPECIFICATION forming part of Letters Patentl No. 286,038, dated October 2, 183,

Application filed March 19, 1883. (No model.)

To all whom, it may concern:

-Be it known that I, THOMAS J. llfIAYAim, of

Reading, in the county of Middlesex and Commonwealth of Massachusetts, have invented a 5 new and improved machine for applying rub` ber-compound liuid cement, whi eh I call Mayall Cement, and flock to cloth to prgduce a water-proof cloth, which I designate Mayall Cloth, of which the following is a specifica- Io tion.

My invention relates to devices for evenly spreading the tluid cement on the surface of cloth, and for laying the fiock evenly on the surface ofthe cement, and for pressing the :flock onto and into the cement, s0 that it will firmly adhere, the object of the invention being 4to provide a convenient and economical apparatusto produce, with common cotton or linen cloth and rubber cement .and iiock, the

water proof cloth which I term Mayall cloth, and it consists in the cons ructionand arrangement of the machine and its various` parts, as hereinafter described.

In the drawings annexed, Figure l shows a 2 5 side view ofthe machine containing and supporting the operating devices, and a frame or table supporting a movable roll, over and v around which the cloth: to be treated passes. Fig. 2 shows a top view of the machine and 3o table withl a loop 'of cloth in process 011 it. Fig. 3 shows a longitudinal section through the machine as shown in Figs. l and 2.

I will call the left-hand end of the machine, as shown in the drawings, the forward7 and the" right-hand the "1-ear end of the machine.

ais a drawing-pulley on the end ofthe shaft which passes through the main roll in the machine, by which the cloth is moved for- 4o wardv during the process.

cis the shaft on whichthe drawing-pulley a and the main roll and the gear and pulley actuating the pressure-'roll and the brushingroll are supported.

a? is the main roll of the machine, by which the cloth is moved forward.

ai is a pulley on the shaft c', over which a belt passes, which moves the blruslrroll.

a* is a belt from and over the pulley a and 5o the pulley on the shaft of tl1e'brush-roll.

a5 is a pressureroll, with a counterpart under it, between which the cloth passes after the iiock has been deposited on it.

a is the brush-roll.

c? is a gear on' the shaft c. 5

cg is an intermediate `gear between the gear aT and the gear on the end of the pressureroll ci.

a9 is a gear on the end of the pressu re-roll .5.

e is a knife with str: ight edge, extending 6. across and supported by standards on each side of the machine, against the edge of which, and at Vright angles to it, the cloth is drawn forward to evenly spread the cement upon it.

c is a trough under the knife c and below 6v the cloth, extending across the machine and resting on the frame of it, into which any fluid cement which may-run over the edge ,of the cloth will fall.

cl is a roll below and a little to the rear of 7( the brnslrroll, over which the cloth passes, the purpose of it being to keep the cloth up close to the under side of the brush-roll. f

c is a supporting-roll at the rear of the knife e, over which the cloth nieves, its purpose being to keep the cloth up to the edge of the knife, so that it will. scrape the surface ol' the ,cloth and evenly distribute the iiuid cement on the surface of it.

e" is a roll mounted on a shaft which is sup; ported in movable or sliding bearings resting on the frame ofthe table, so that the roll mayl be moved forward and backward on the ma-` chine, as circumstances may require, and over andV around :which the loop of cloth in process passes.

ci is a roll with a crank to turn it, and cords which wind up on it by turning it, which are attached to arms extending from the roll c4, so that by turning` this roll bythe crank the roll c is drawn toward the rear endl of the 1nachine, the purpose of this being to give greater or less tension to the loop of cloth in the machine while in process.

e is a loop of cloth extending over and around the main roll ai, the ends of the cloth being ljoined by cement or otherwise, so as to make a loop or link of it. This loop of cloth passes between the pressure-rolls c5, under the brush-roll c, over the supportingpulley e?, under the edge of the knife c, over the trough e and the support-ingroll IOC c. and over and around the roll el, and forward below all the rolls to the roll ai, moving, when the machine is operating, in the direction indicated by the arrow x.

cl is a trough extending across the machine, and supported at each end on frames resting on the side frames of the machine, having a funnel-shaped bottom with openings through it. The iluid kcement to be spread upon the cloth is put into this trough. rlhe openings are so graduated that a sufficient quantity of the fluid cement will pass through onto the upper surface of the cloth to be covered by it, and they can be wholly closed at plea-sure.

y cE is a trough similar to the trough cl, into whichv the flock to be deposited on the cementcovered cloth below is placed, in the bottom of which are suitable openings to permit the iloek to fall through onto the cloth below. ln the bottom of this trough a device for stirring the flock to make it fall uniformly may be placed, if necessary.

The operation ofthe machine is this: A piece of suitable cloth is cut long enough to reach around the main roll c and the roll c, and put around these rolls, and the ends joined by ccment or otherwise. The'proper degree of ten- -siou is given to the cloth by turning the crank of the roll and fastening it at the right point. Fluid cement is placed in the trough el. Flock lis placed in the trough cH. The rolls'are put in motion, carrying the loop of lcloth toward and around the main roll at the forward end ofthe machinel AThe fluid cement falls on the cloth, andas it passes unde'l.I the knife itis evenly 'distributed by it over the whole width, tl knife-edge so pressing against the upper surface of the cloth that all the surplus cement, after giving the cloth the thinnest possible coating, is retained at the rear of the knife,

and as the quantity accumulates behind the knife it falls over the edge of the cloth into the trough c. JVhen the surface of the cloth covered with cement comes under the trough of iiock, the passages through the bottom of it yare opened and the flock is made to fall from it upon the whole width of thc cloth. As the cloth is carriedy still fart-her forward the brushroll evenly distributes the flock on the cemented surface ofthe cloth and rubs it against and into the cement. This surplus will fall. into a suitable receptacle prepared to receive it under the machine, and from rtime to time returned to the trough from which it fell. As the motion of the machine continues the cc mented and flocked surface of the cloth comes under the pressure-roll c, which, acting by quantity or springs, as tl iecase maybe, presses the flock against and into the cement on the cloth.'v NVhen the whole loop of cloth has been treated in this way, it should be carefully examined with a nutgnilying-glass, and if it is found that the cement. can be seen above the flock it should be again run around, while the ccment-trough 'is closed and another dressing of flock deposited on it and pressed in by the roll, as before, when it will be :found that the cement will be completely covered by the flock.

rllhe loop of cloth will then be removed and placed in a suitable place to dry, and when the cement is dried it will be ready for use or sale. lt is not necessary to cu re the rubber or cloth treated as descri bed with the lvllayall cement by sun or artificial heat, ashas been necessary with what has been termed gossainer rubber clotln7 the character of the Mayall cement, derived from its component substances, rendering that unnecessary, while at the same time its superior strength and adhesive tenacity and 'pliability inake the con'iplcted product, which l term llfayall cloth,7 indestructi ble by ordinary wear and fair usage. llt will of eoursetear if suliicient force is applied; but it will, resist much more than the ordina-ry rubber-coated. cloth, or gossamcr, l as it is called.

l claim. as new and of iny .invention- The above-described improved machine for applying and afiixing cement and iioek to cloth, consisting of the rolls ci, a, a, e2, c, c", and c5, the knife e, and the troughs al and c, in combination with suitable supporting and driving devices, all substantially as set forth.

THOS. .T. MA'YALL.
